Single tool with partial schema definition. Tool name lacks action verb (should be 'evaluate_research_consensus' or 'verify_consensus'). Description is adequate (95 chars, within 10-1024 range) but generic. Input schema present with types and descriptions for all parameters, but output schema is completely undocumented, LLMs cannot plan downstream calls or extract structured data. No error handling guidance, no recovery paths, no validation rules in descriptions. Parameter 'claims' defaults to null with no guidance on required structure. Tool does not declare what it returns or how to interpret the verdict field.

• Rename tool to 'evaluate_research_consensus' or 'assess_consensus_claims' to start with a clear action verb. This helps LLMs infer intent from the name alone.
• Document the complete output schema with field types and descriptions. Example: {verdict: enum[HIGH_CONSENSUS_VERIFIED|MODERATE_DISPUTED], consensus_score: number[0-1], evaluated_claims: array[{statement: string, net_credibility: number}], ...}
• Add validation rules to parameter descriptions: 'claims (required): array of 1-50 claim objects. Each claim must have statement (string, 1-500 chars), source_url (valid HTTP/HTTPS URL), year (integer, 1900-2100), confidence (number, 0.0-1.0).'
• Add error handling guidance: 'Returns error if claims array is empty, malformed, or contains invalid confidence scores. Error response includes the invalid field and expected format.'
• Specify what 'verdict' values mean and when to use them. Add enum constraint: verdict in [HIGH_CONSENSUS_VERIFIED, MODERATE_DISPUTED, INSUFFICIENT_DATA]. Document decision thresholds in description.
